Sprint Intensity Training to overtake HIIT?

The Sprint 8® Protocol is more intense than interval training, but worth the effort, according to its creator Phil Campbell.

In two hospital-based studies specifically on Campbell’s Sprint 8 Protocol, the research shows an average drop in body fat of 27% with no change in diet. Campbell attributes the results to a natural increase in human growth hormone.
